Polypropylene

Uneven cooling creates internal stresses that cause warpage. Better mold cooling improves dimensional stability and part quality.

Polyolefins dominate healthcare packaging, but low recycling rates reveal a major sustainability gap in medical plastics waste.

Bio-based additives support sustainable plastics, but cost premiums, feedstock volatility, and compliance pressure complicate adoption.

Measuring microplastics requires reliable detection, contamination control, validated methods, and reproducible analytical results.

Mechanical recycling can change the color response, surface quality, and mechanical performance of thermochromic polypropylene used in smart packaging.

The SPE Microplastics Forum takes place in Baltimore, Maryland, on Oct. 20–21, 2026, covering detection, regulation, and solutions.

Better collection systems can reduce contamination and improve the quality of recycled plastic feedstock before sorting, washing, and extrusion begin.

Flexloop uses solvent extraction to remove inks, adhesives, odors, and contaminants from flexible films, enabling higher-quality recycled resin.

LEGO is reducing emissions and expanding the use of renewable, recycled, and mass-balance plastics across its global toy portfolio and supply chain.

Petrochemical feedstock strategy is shifting from lowest cost toward flexibility, carbon reduction, and geopolitical resilience.
